ASUS Eee PC 1000H Under The Covers - The Chipset and CPU Detailed

By: John Freeman | Netbooks (EOL) in Laptops | Posted: Jun 21, 2008 4:00 am

Intel Atom™ Processor with Mobile Intel 945GSE Express Chipset


Atom is the new Intel CPU for mobile platforms, formerly called Diamondville. It works in conjunction with the M 945GSE controller chipset which has a controller hub based on the ICH7 south bridge chipset, originally prevalent on larger ATX platform motherboards. According to Intel, the Atom processor is a completely new hafnium-based 45nm microarchitecture design to combine energy efficiency with super processing power.


This first generation of the Atom is single cored with hyperthreading, meaning that it simulates two cores inside its single core. These processors will become more prevalent as more and more Mobile Internet Devices (MID's), UMPC's and mini-PC's get launched over the coming weeks and months. Intel believes it will be the best choice for all consumers, and the main reason for that is the performance per watt advantages. Those advantages are a sub 1 to 4 watt thermal power envelope for web browsing based applications; the second benefit is the scaling of power usage, which can switch anywhere between 800MHz to 1.86GHz. Lastly, the FSB is set at 533 MHz, enabling faster data transfer rates between the core subsystems.


The Eee PC has tapped into the Atoms capabilities by enabling button controlled power scalability. Thus, at just the touch of a button your Eee PC can be at full power or sleeping contently, waiting for your next wake up call. Basically, she's a partner that dreams are made of.


You can view the CPU in the picture below; this is a 1.60GHz Atom with 512K cache, running on a 533MHz FSB.

Lastly, you can see the 82801GBM I/O Controller Hub (ICH7M). This chip has integrated HD Audio, AC'97 Audio, Integrated graphics with an independent display option and UXGA viewable output.
